Definitions

  • This invention relates to a new method for co- producing fuel and metallized iron from coal and from iron ore respectively.
  • the metallized iron is also known as"directly reduced iron” (DRI) .
  • the present invention overcomes the above disadvantages and provides an efficient method which, while producing fuel in the form of coke and/or gas can also co-produce DRI from iron ore, utilizing abundant coal as a base.
  • DRAWINGS The embodiment of the invention is illustrated in the accompanying drawings, in which:
  • Figure 1 is a flow diagram illustrating the co- production of coke and DRI in which the DRI is fed while hot into a covered insulated container for charging directly into a steel making furnace.
  • Figure 2 is a flow diagram illustrating the co- production of coke and DRI in which the DRI is fed directly into an electric arc steel making furnace and the coke into a blast furnace.
  • Figure 3 is a flow diagram illustrating the co- production of coke and DRI in which the DRI is melted in a furnace prior to its being charged into an oxygen steel making furnace.
  • coke shall herein be inclusive of coke which is made from metallurgical coals and utilized for smelting iron such as in a blast furnace, and also of coke which is known as "char” which is made from non-metallurgical coals and is used for making gaseous fuel in a gasifier; such fuel being utilized for other purposes including the generation of electricity.
  • numeral 10 is the retort in which the coal is heated in the absence of oxygen.
  • the coal is introduced as shown by arrow 11 and the hot flue gas is introduced to heat the coal as shown by the arrow 12.
  • the flue gas after heating the coal indirectly exits retort 10 at point 13.
  • the coke is discharged as shown by arrow 14 and the raw coal gas exits retort 10 as illustrated by arrow 15.
  • the coke is exported for use as a fuel to a furnace such as a blast furnace, shown in Figure 2 and marked by numeral 16, or the coke is gasified in a gasifier (not shown) to produce a gas to be used as fuel for electric power generation for the electric arc furnace shown in Figure 2 and denoted by numeral 50.
  • a gasifier not shown
  • cracking unit 17 holds the reagent against which the hydrocarbons contained in the raw gas are cracked.
  • cracking unit 17 is made into two parts; an upper chamber denoted by numeral 20 which is used to regenerate the reagent and a lower chamber denoted by numeral 21 which is used for the cracking operation proper.
  • the reagent is recycled from the bottom of chamber 21 to the top of chamber 20 as shown by arrows 22 and 23.
  • the gas leaving chamber 21 as shown by arrow 19 is a cracked, desulfurized, hot reducing synthetic gas which is highly reactive with iron ore; this synthetic gas enters reducing shaft 24 as shown by arrow 25.
  • Reducing shaft 24 is also preferably made into two parts; an upper part denoted by numeral 26 which serves as the preheating zone for the iron ore prior to the reduction reaction, and a lower part denoted by numeral 27 which serves as the reducing reaction zone for converting the ore to DRI.
  • the flue gas enters preheating zone at point 45 and exits at point 46.
  • the iron ore which is in pellet form is introduced into the top of shaft 24 as shown by arrow 47.
  • the synthetic gas after the reducing reaction leaves zone 27 as shown by arrow 28 as an off-gas.
  • This off-gas which still possesses utilitarian value is first used to preheat combustion air in heat exchanger 29; this combustion air enters as shown by arrow 30 and exits as shown by arrow 31.
  • the off-gas after being cooled in heat exchanger 29 is boosted in pressure by blower (compressor) 32 and is divided into stream 33 and stream 34; stream 34 is further divided into stream 35 and stream 36.
  • Stream 33 is a first portion of the off- gas which joins raw gas stream 15 to form stream 18 and is thus recycled.
  • Stream 35 is a second portion of the off-gas which is combusted in burner 37 to provide the thermal energy required for heating the coal to make the coke and generate the raw coal gas.
  • Stream 36 is a third portion of the off-gas which is purged in order to maintain the process in balance; this third portion is also used for other thermal energy needs.
  • the coal is introduced at point 11 of retort 10 and the ore at point 47 of reducing shaft 24.
  • the coke is directed via stream 14 to either a blast furnace or a gasifier; the DRI is fed into insulated container 48 in order to accept the DRI while still hot, thus minimizing heat loss.
  • the oxygen steel making furnace denoted by numeral 49, receives a charge of molten iron (arrow 51), scrap
  • Stream 14 could represent metallurgical coke if metallurgical coals are used in retort 10; stream 14 could also represent a non- metallurgical coke (char) if non-metallurgical coals are used in retort 10.
  • Stream 14 (the coke stream) is directed to blast furnace 16 where iron ore (stream 58) and stone (stream 59) are added to the coke.
  • a blast of air (stream 57) is introduced at the bottom of blast furnace 16.
  • the DRI is fed directly into electric arc furnace 50 via steam 56, and steel is tapped as shown by stream 60.
  • Stream 56 (the DRI stream) is fed into a melting furnace denoted by numeral 61 and the purge gas (stream 36) is used to fuel furnace 61.
  • Air (stream 62) and flux (stream 63) are added in order to convert the DRI to molten metal which is charged into steel making furnace 49 by means of transfer car 64 and ladle 51.
  • the slag is collected in cinder pot 65.
  • stream 14 is directed to a gasifier (not shown) and the coke is converted to a gas which is then used as a fuel to generate electricity; this electricity can be utilized for various energy needs inclusive of the operation of the electric arc furnace shown in Figure 2.
  • a gasifier not shown
  • other carbonaceous material may be added to the charge, as for example, tires, biomass, paper, plastics, etc.

Abstract

La présente invention concerne un procédé de production combinée de combustible et de fer à partir de charbon (11) et de minerai de fer (47) respectivement. Ce procédé comprend le chauffage du charbon en l'absence d'oxygène, pour produire un gaz de houille brut et un coke résiduel, et l'augmentation de la proportion d'hydrogène libre dans le gaz par craquage, au contact d'un réactif très chaud produisant une désulfuration, des hydrocarbures contenus dans le gaz afin de produire un gaz synthétique de réduction (25) à chaud, riche en hydrogène et désulfuré. Ce gaz synthétique (25), qui est hautement réactif, est envoyé à travers un lit de minerai de fer afin de le réduire directement, donnant de l'éponge de fer (56).
